    Presented at the Central Plains irrigation conference on February 16-17, 2005 in Sterling, Colorado.Crop responses to MESA (mid-elevation spray application), LESA (low-elevation spray applicator), LEPA, (low energy precision application), and SDI (subsurface drip irrigation) were compared for full and deficit irrigation rates in the Texas Panhandle. Crops included three seasons of grain sorghum and one season of cotton; crop responses consisted of economic yield, seasonal water use, and water use efficiency (WUE). Irrigation rates were I0, I25, I50, I75, and I100 (where the subscript denotes the percentage of full irrigation, and I0 is dryland). Yield and WUE was greatest for SDI and least for spray at the I25 and I50 rates, and greatest for spray at the I100 rate. Yield and WUE trends were not consistent at the I75 rate. Seasonal water use was not significantly different in most cases between irrigation methods within a given irrigation rate. For cotton, the irrigation method did not influence boll maturity rates, but SDI resulted in higher fiber quality at the I25, I50, and I100 rates

    Presented at the 21st annual Central Plains irrigation conference on February 24-25, 2009 in Colby, Kansas.Crop production was compared under subsurface drip irrigation (SDI), low energy precision applicators (LEPA), low elevation spray applicators (LESA), and mid elevation spray applicators (MESA) at the USDA-Agricultural Research Service Conservation and Production Research Laboratory, Bushland, Tex., USA. Each irrigation method was compared at irrigation rates meeting 25, 50, 75, and 100% of full crop evapotranspiration (ETc). Crops included three seasons of grain sorghum, one season of soybean (planted following a cotton crop that was destroyed by hail), and four seasons of upland cotton. For grain sorghum, SDI followed by LEPA, MESA, and LESA resulted in greater grain yield, water use efficiency, and irrigation water use efficiency at the 25- and 50% irrigation rates, whereas MESA followed by LESA outperformed LEPA and SDI at the 75- and 100% irrigation rates. For soybean, the same trend was observed at the 25- and 50% irrigation rates, whereas SDI followed by MESA, LEPA, and LESA resulted in the best crop response at the 75% irrigation rate, and MESA followed by SDI, LESA, and LEPA resulted in the best crop response at the 100% irrigation rate. Cotton response was consistently best for SDI, followed by LEPA, and either MESA or LESA at all irrigation rates. Within each irrigation rate, few significant differences were observed among irrigation methods in total seasonal water use for all crops

    Presented at Proceedings of the 23rd annual Central Plains irrigation conference held in Burlington, Colorado on February 22-23, 2011.Corn is a major irrigated crop in the U.S. Great Plains with a large irrigation requirement making efficient, effective irrigation technology important. The objective of this paper was to compare corn productivity for different irrigation methods and irrigation rates in 2009 and 2010 at Bushland, Texas. Irrigation methods included mid-elevation spray application (MESA), low elevation spray application (LESA), low energy precision application (LEPA), and subsurface drip irrigation (SDI). Each irrigation method was evaluated at four irrigation rates, which were 25, 50, 75, and 100% of meeting the full crop water requirement. There were no significant differences in grain yield and water use efficiency for MESA, LESA, and SDI for the 100% irrigation rate in 2009 and for all irrigation rates in 2010. In 2009, SDI resulted in significantly greater grain yield and water use efficiency compared with all other methods at the 50 and 75% irrigation rates; little measurable grain yield resulted for all methods at the 25% rate. However, 2009 was not a typical production year because an irrigation system failure occurred just before anthesis, and unusually high atmospheric demands followed, resulting in soil water shortages in all plots during the most water-sensitive development stages, with consistent lowering of grain yield. In both years, LEPA resulted in lower yield, soil water content, and water use efficiency compared with the other methods at the 75 and 100% rates, which was partially attributed to furrow dike erosion and plot runoff. The relative response of corn to MESA, LESA, LEPA, and SDI was much different compared with other crops that were evaluated in previous experiments; these included grain sorghum, soybean, and cotton

    BOGOO : Warisan Perahu Komuniti Bajau Laut DI Sabah, Malaysia

    The Bajau Laut (Samal) people, also known as pala’u, is among the Bajau ethnic tribes in the east coast of Sabah who are still practicing the sea nomads lifestyle. They are synonym with the lepa-lepa, a boat in which they live on the sea. In the effort to preserve this heritage and culture, the Ministry of Culture, Arts and Tourism of Sabah has gazette the “Lepa-Lepa Regatta” in the Sabah tourism calendar. Other than Lepa-Lepa, the Bajau Laut community actually treasures another sampan design that is unique only to the tribe. It is the winged sampan called bogoo that is used for fishing. Nevertheless, this unique heritage and culture has never been exposed to the public by any scholar studying this subject. This article is written for the purpose of documenting the sampan as one of the heritage and culture of the Bajau Laut community in order to avoid the disappearance of this culture to the development. This writing is based on the field work done by the author regarding the tradition of Bajau Laut community in the east coast of Sabah in Mac 2007

    Why mesological Pedagogy?

    No full text
    Problems of the environment are of concern, among others, to social pedagogy. The subject of research in the field is very large and is still expanding. This can be noticed in the case of media, whose rapid development brings forth new questions and pedagogical dilemmas. This paper refers to an attempt to establish mesological pedagogy as a branch of educational sciences. The attempt was undertaken in Western Europe in 1950s. Mesological pedagogy is concerned solely with the pedagogical aspect of the environments of human beings (family, school, workplace, religious community, etc.). As indicated by the etymology of its name, it is a study of the environment. Therefore, the author of this paper presents reasons for the continuation of research in the field of mesological pedagogy. This will be of benefit to social pedagogy and will open new directions of development in the broad study of the environments of contemporary humans

Šī tēma ir aktuāla, jo problēmas, kas saistītas ar spēju uzlabot mutvārdu tekstu veidošanu krievu (svešvalodu) valodas stundās, ir diezgan daudzveidīgas un diezgan aktuālas mūsdienu skolā. Jāatzīmē, ka, sākot mācīties svešvalodu, skolēni pirmām kārtām vēlas iemācīties runāt šajā valodā. Tomēr iemācīties runāt ir diezgan sarežģīts process, kas sastāv no daudziem komponentiem. Šajā diplomdarbā darba autore analizē runāšanas lomu svešvalodas apguves procesā; apkopo to zinātnieku lingvodidaktiskās pieredzes, kuru uzmanības centrā ir metodes un paņēmieni skolēnu runāšanas prasmju attīstīšanai svešvalodā; raksturo grūtības, ar kurām sastopas skolēni, veidojot mutvārdu tekstus svešvalodā. Diplomdarba praktiskajā daļā darba autore izklāsta pašas veiktā praktiskā pētījuma gaitu: 6. klases skolēnu un svešvalodu skolotāju aptaujas rezultāti; skolēnu runāšanas līmeņa pārbaude (sākotnējā kontrole); didaktisko materiālu aprobācijas process; apkopoti praktiskā pētījuma rezultāti.

This study is devoted to the study of the didactic possibilities of the formation and development of speaking skills in the lessons of the Russian language as a foreign language for schoolchildren of grades 6 in a Latvian school. This topic is relevant because problems associated with improving the ability to create verbal texts in the lessons of the Russian (foreign) language are quite diverse and quite relevant in a modern school. It should be noted that when starting to learn a foreign language, schoolchildren primarily want to learn how to speak this language. However, learning to speak is a rather complicated process, consisting of many components. In this diploma paper, the author analyzes the role of speaking in the process of mastering a foreign language; summarizes the linguodidactic experience of scientists whose focus is on methods and techniques for developing schoolchildren' skills in speaking a foreign language; characterizes the difficulties encountered by schoolchildren in the process of creating verbal texts in a foreign language. In the practical part of the diploma paper, the author describes the course of her own practical research: the results of a survey of schoolchildren in grade 6 and teachers of foreign languages; testing (initial control) of schoolchildren speaking level; the process of approbation of didactic materials; summarizes the results of a practical study. This paper may be useful to methodologists, teachers, researchers interested in the development of modern theory and practice of teaching foreign languages. Кey words: speaking, monologue, foreign language, methods and techniques, communicative and speech skills

    Scientific interests of Bishop dr. Adam Lepa focus on family as the environment of socialization and upbringing, and on the mass media. He is interested in both negative and positive effects of the media on the life of an individual, family and society, and in the first place, in how to use the media in a creative way and prepare, especially children and young people, to this task. These themes were discussed in 9 books (Pedagogika mediów [Media pedagogics] had 3 editions), 162 scientific articles in collective works and journals, 105 popular articles, 242 commentaries and 90 interviews in various magazines, he has published until 2007. In his works, he competently analyzes present social, family, educational, religious, moral, political and economic problems. He is one of the best known and most cited authors specializing in the area of propaganda and manipulation, as well as in the media pedagogics. He is author of the original theory of the media environment whose main components are the iconosphere and the logosphere; nowadays the iconospehere dominates over the logosphere, while they should remain in harmony. School and family have the best conditions to organize the logosphere, and they should be the first to prepare the young generation to make an appropriate use of the media. In his works, Bishop dr. Adam Lepa connects the theory and the practice. His scientific attainments has interdisciplinary character and closely connected with pedagogics, sociology, sociology of education, communication and journalism, ethics, pastoral theology. The works of Bishop dr. Adam Lepa make a great contribution to these subdisciplines. In his scientific research, Bishop dr. A. Lepa always shows concern for man, for man's ability to use the modern media competently and make them serve his development. Being a wise and good person, Bishop Lepa creates a „civilization of the future” based – in agreement with the thought of the Holy Father John Paul II – on the culture of love and peace
